The War God's Rejected Daughter Wields a Mace

One-sentence synopsis: A six-year-old demigod girl abandoned by her war god father enters a magic academy to escape the fate of dying or going out of control in three months. She unexpectedly subjugates a giant's divine artifact, fights for the life-saving divine spring accompanied by two companions and a group of teachers, and finally learns to control her power in the disaster created by the moon god's agent, turning her hands that were once enough to destroy the gods into ones that can finally hold her mother gently.
